MR24-30-TX 2.4GHz LoRa Transmitter Module with MRx-Tx Adapter

The mR24-30-TX is a high-performance 2.4GHz LoRa transmitter module, perfect for enhancing long-range communication in UAVs and other remote control applications. Powered by the STM32G431KB MCU and mLRS firmware, this module features the LoRa SX1281 with TCXO, delivering reliable RF power options from 13dBm to 30dBm (1000mW). The module includes an IPEX MHF-1 antenna connector and comes with SMA and RP-SMA adapter cables for flexible antenna configurations.

The mRx-Tx Adapter is equipped with a built-in HC-04 Bluetooth module and a 5V fan controller that activates when the output power reaches 500mW, ensuring optimal performance. The adapter also includes a one-button interface for DFU mode and binding, along with LED indicators to display mLRS and Bluetooth status. Power the adapter with a 5-13V DC supply through the JR_PIN3 (VIN) connection.

Designed for easy integration, the mR24-30-TX module and mRx-Tx Adapter are ideal for those looking to upgrade their UAV systems with robust and flexible communication capabilities.
